1. What is the Ideal Gas Law?

The Ideal Gas Law (V = nRT/P) describes the relationship between pressure, volume, temperature, and number of moles of an ideal gas. It combines Boyle's Law, Charles's Law, and Avogadro's Law into a single equation.

2. How Does the Calculator Work?

The calculator uses the Ideal Gas Law equation:

Where:

• \( V \) — Volume (L)
• \( n \) — Moles of gas (mol)
• \( R \) — Gas constant = 0.0821 L·atm/(mol·K)
• \( T \) — Temperature (K)
• \( P \) — Pressure (atm)

Explanation: The equation calculates the volume occupied by a given number of moles of an ideal gas at specified temperature and pressure conditions.

3. Importance of Volume Calculation

Details: Accurate volume calculation is crucial for chemical reactions, gas storage design, industrial processes, and understanding gas behavior under different conditions.

4. Using the Calculator

Tips: Enter moles in mol, temperature in Kelvin, and pressure in atm. All values must be positive (moles > 0, temperature > 0, pressure > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is an ideal gas?
A: An ideal gas is a theoretical gas that follows the ideal gas law exactly, with particles that have no volume and no intermolecular forces.

Q2: When is the ideal gas law not accurate?
A: At high pressures and low temperatures, real gases deviate from ideal behavior due to molecular volume and intermolecular forces.

Q3: How do I convert Celsius to Kelvin?
A: Add 273.15 to the Celsius temperature: K = °C + 273.15

Q4: What other units can be used for pressure?
A: Pressure can be in mmHg, kPa, or bar, but the gas constant value must be adjusted accordingly.

Q5: Can this calculator be used for gas mixtures?
A: Yes, for ideal gas mixtures, use the total number of moles of all gases present.
